| Question | Answer |
|---|---|
| Surface tension | the elastic-like "skin" or force at the surface of a liquid, caused by the strong attraction between liquid molecules, which pulls them inward and |
| Solvent | a substance, typically a liquid but sometimes a solid, gas, or supercritical fluid, that dissolves another |
| Specific heat | the amount of heat energy required to raise the temperature of one unit of mass of a substance by one degree Celsius |
| Evaporation | the process where a substance, typically a liquid, transforms into a gas or vapor, driven by heat energy |
| Condensation | the process where a gas, like water vapor, changes into a liquid |
| Freezing | becoming very cold or turning from a liquid to a solid due to loss of heat |
| Melting | the physical process where a substance changes from a solid to a liquid state, typically due to increased heat energy |
| Boiling | a liquid heated to its boiling point, causing it to bubble and turn into vapor |
| Capillary action | the movement of a liquid through a narrow space without the help of, and sometimes in opposition to, external forces like gravity |
| Universal solvent | a substance that can dissolve a vast number of different substances, though not literally all of them |
| Mechanical weathering | the physical breakdown of rocks into smaller pieces without changing their chemical composition |
| Chemical weathering | the breakdown and alteration of rocks and minerals through chemical reactions with agents like water, oxygen, carbon dioxide, and acids, resulting in new compounds or dissolved substances |
| Erosion | gradual destruction and wearing away of a surface by wind, water, glaciers, or other natural elements |
| Sediment | solid material, like soil, sand, or rock fragments, that is transported by natural forces such as water, wind, or ice and then deposited in another location, often settling at the bottom of a liquid or forming layers on the Earth's surface |
| Deposition | but most commonly refers to the taking of sworn oral testimony from a witness before a trial, used for legal discovery and to preserve |
| Mass movement | the downslope movement of rock, debris, or sediment primarily due to gravity |
| Deflation | a broad, sustained decrease in the general price level of goods and services across an entire economy |
| Sand dune | the passage of time and the changing nature of life. |
| Loess | "loose" or "crumbly," |
| Stream | a continuous, steady flow of liquid, light, or people |
| Tributary | the Missouri and Ohio rivers flowing into the Mississippi River, the lrtysh River flowing into the Ob River, the Feather River flowing into the Sacramento River, and the Shenandoah River with its North and South forks feeding into the main river |
| Flood plain | a flat area of land next to a river, lake, or ocean that is subject to flooding during periods of high water |
| Delta | a landform created by river sediment accumulation, a symbol (Δ or δ) representing change, or a component in electrical systems |
| Alluvial fan | a fan-shaped landform created when a fast-moving mountain stream emerges onto a flat valley, causing the water to slow down and deposit the sediment it carries, forming a broad, sloping deposit of mud, sand, gravel, and boulders over time |
| Groundwater | water held underground in the saturated zones of soil, pores, and cracks in rocks, forming aquifers |
| Glacier | a huge, slow-moving mass of ice, formed on land from compacted snow, that flows down a slope, valley, or spreads out across a land surface under its own weight and gravity |
| Continental glacier | a massive, continuous body of ice that covers a vast area of land, typically a continent or large island, and is not confined by surrounding topography |
| ice age | a geological period characterized by a significant and extended drop in Earth's global temperatures, leading to the formation and expansion of continental ice sheets and glaciers across vast areas of the planet |
| valley glacier | a type of glacier found in mountainous regions that flows downhill between the walls of a valley |
| Plucking | to remove something with a sudden pull, such as feathers from a bird, fruit from a tree, or hair from a body |
| Till | unsorted, unstratified sediment deposited directly by a moving glacier |
| Longshore drift | the zigzag movement of sediment, such as sand and pebbles, along a coast caused by waves approaching the shore at an angle |
| runoff | precipitation (like rain or melted snow) that flows over the land surface instead of soaking into the ground, eventually moving into rivers, lakes, and oceans. |
